Light-Filled Steel French Doors for Connected Spaces

A single leaf, a pair with fixed or opening sidelights, an overhead transom, or a full screen wall, each configuration is shaped around how you actually use your rooms. Thermally broken steel profiles ensure compliance with UK U-value regulations, while double glazing and 6mm toughened safety glass come as standard. Triple glazing and laminated upgrades are available where acoustic performance or impact resistance is a priority.

Statement Double Steel Doors for Dramatic Openings

Wider apertures deserve a grander treatment. Our double door collection spans classic French pairs, sidelight combinations, transom-topped sets, and full-height screens. Arched variations are available as a fully curved frame or a shaped transom above a standard rectangular pair. Every hinge, handle, glazing bar, and frame is fabricated in steel, fitted with 6mm toughened safety glass throughout. Laminated glazing can be specified for enhanced protection.
